Compilation fails in Visual Micro, works in Arduino IDE (STM32duino)

Hi, 

I get the following compilation error in Visual Micro, while compilation in the Arduino IDE works fine.

I guess it has to do with the included library code (qp framework), as I can compile a standard "blinky" sketch not using that framework.

BlinkyQP.ino: 26:7: error: expected nested-name-specifier before 'void
   26 | void setup() {
   |       ^~~~

Thanks,
Bernhard

Might be some C++ name mangling.

It works in VM if I define setup() as external C:

extern "C" void setup() {...}

Best regards,
Bernhard

Thanks for the report and the detail around this, we can now replicate the issue and will continue to investigate.

The issue is related to the prototype generation, which in this case is generating an incorrect prototype for the setup() function.

A work around while we investigate further (in this specific case), is to add a dummy variable declaration between "using namespace QP;" and "void setup()"
e.g. 
Code
Select All
using namespace QP;

int dummyVar = 0;

void setup() {
